We have published at
the application template for a simple control system: sensor publishes periodic telemetry to Losant,
Losant workflow checks if above a high or low threshold, and sends control message to actuator
to turn on or off, respectively. This 2 minute video shows it in action:
To the first 3 commenters on this thread (or via PM, if you prefer) we will send the URL to an online lab to interoperate with this application.
This allows you to easily investigate bi-directional control (telemetry received and commands sent) in Losant.
